摘要： The invention relates to a method for preparing lead (212) for medical use. This method comprises the production of lead (212) by the decay of radium (224) in a generator comprising a solid medium to which the radium (224) is bound, followed by the extraction of the lead (212) from the generator in the form of an aqueous solution A1, characterized in that the lead (212) contained in the aqueous solution A1 is purified from the radiological and chemical impurities, also contained in said aqueous solution, by a liquid chromatography on a column. The invention also relates to an apparatus specially designed for automated implementation in a closed system of said method. It further relates to lead (212) produced by means of this method and this apparatus. Applications: manufacture of radiopharmaceuticals based on lead (212), useful in nuclear medicine for the treatment of cancers, particularly by a-radioimmunotherapy, or for medical imaging, in both humans and animals.

摘要： A method for reducing tin in lead bullion has the steps of adding an Arrhenius base to a kettle containing lead bullion and tin, adding a byproduct of conventional detinning to the kettle, agitating contents of the kettle, and removing a layer of slag from the kettle. The disclosed method removes tin via chemical oxidation, adds lead via chemical reduction of an oxide from the byproduct of conventional detinning, and preserves most of the antimony content of the lead bullion.

摘要： In the refining of crude lead, particular constituents such as arsenic, tin and antimony are removed either by selective oxidation by means of air or oxygen or by selective oxidation by means of a salt slag. In the selective oxidation by means of air or oxygen, the oxidant is blown by means of a lance into a bath of liquid lead. A disadvantage of the processes according to the prior art is that a considerable part of the oxidant blown in escapes unused. To improve the efficiency of a process for removing arsenic, tin and antimony from crude lead which operates using a gaseous oxidant, it is proposed according to the invention that the oxidant be introduced in the form of small gas bubbles into a bath of liquid crude lead. As a result of the large surface area of the gas bubbles introduced and the increased residence time, in particular when small gas bubbles are produced in the bath, the reaction is significantly accelerated compared to known processes.

摘要： A novel alloy for use in lead refining is disclosed which comprises magnesium and calcium. The preferred ratio on a weight basis of magnesium to calcium is between 1.2 and 5.2. A method of adding this alloy to a lead bath is described which brings calcium into solution with the lead and provides a high recovery ratio.

摘要： Un procede de purification de coulees, consistant sensiblement en metaux non ferreux, de preference du cuivre et du plomb, par elimination des impuretes contenues sous forme d'elements qui ne sont pas separables facilement, tels que le cobalt, le nickel, le plomb, le bismuth, l'antimoine et l'arsenic, consiste a injecter dans la coulee au moins un agent de reaction solide a l'aide d'un gaz porteur. Pendant le procede d'injection, la coulee est maintenue sous l'influence de turbulences importantes. Le gaz porteur et l'agent de reaction solide sont selectionnes de sorte qu'il se forme avec l'element ou les elements d'impurete un produit dont le point de fusion est superieur a la temperature regnant dans la coulee, et qui possede une densite differente de celle de la coulee. Le produit resultant est alors separe de la coulee. Par exemple, la coulee peut etre constituee de cuivre, et les elements d'impurete peuvent etre du nickel et/ou du cobalt, et l'agent de reaction de la silice, qui forme un produit solide avec le nickel et/ou le cobalt. De maniere appropriee, la coulee peut egalement contenir un agent d'oxydation, tel que l'oxyde de fer (III) ou l'oxyde de cuivre. La coulee peut consister egalement en plomb brut et les elements d'impurete peuvent etre de l'antimoine et/ou de l'arsenic. Dans ce cas, l'agent d'oxydation peut etre de l'oxyde de plomb, qui peut egalement jouer le role d'agent de reaction solide pour former un produit solide. D'autres combinaisons sont egalement concevables.

摘要： Provided is high purity tin or tin alloy wherein the respective contents of U and Th are 5ppb or less, the respective contents of Pb and Bi are 1 ppm or less, and the purity is 5N or higher (provided that this excludes the gas components of O, C, N, H, S and P). This high purity tin or tin alloy is characterized in that the ± ray count of high purity tin having a cast structure is 0.001 cph/cm 2 or less. Since recent semiconductor devices are densified and are of large capacity, there is considerable risk of a soft error occurring due to the influence of the ± ray from materials in the vicinity of the semiconductor chip. In particular, there are strong demands for purifying the soldering material or tin to be used in the vicinity of semiconductor devices, as well as for materials with fewer ± rays. Thus, the present invention aims to provide high purity tin or tin alloy and the manufacturing method of such high purity tin by reducing the ± dose of tin so as to be adaptable as the foregoing material.
